This is a fire control system I designed for
an acquaintence who does pyrotechnics for movie effects and fireworks
displays (he never did come by to look at it)
The control box has 2 banks of 9 "shots" each, they can
be set to fire automatically (the speed is adjustable) or manually
one at a time. It has a keylock for power on, and a two button firing
system. It also has a continuity circuit that runs on 2.1v/20ma
which is enough to light the continuity LED, but not enough to set
off a squib. The controller automatically resets to 0 when the fire
buttons are released, so if you are using it in manual mode, you
have to hold button 1 down until you are finished your sequence.
By using different breakout boxes, you can use the controller to
run anything you want such as
- standard terminal blocks for firing squibs directly (shown)
- a relay box to control lighting FX etc.
- a triac output box for high speed switching of ac voltage devices
I am working on another version that will run on
18 volts (this one is 9v) and will have 6 banks of 9 shots and another
one that will have 10 banks of 9 shots that can be semi /fully automatic
or manual, whether or not I ever finish them will depend on my finances,
and if anyone is interested in them.
